IMPROVEMENT IN CUSPADORES.

Specification forming part of Letters Patent No. 206,843, dated August 6, 1878; application filed August 14, 1877.

To all whom 'it may concern:

Be it known that I, SAML. J. VAN STAVOREN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improved Cuspadore; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it,

reference beinghad to the aeeompanyin g drawings, which form part of this specification, in Whieh- Figures 1 and 2 are broken elevations, partly in section, showing the cuspadore in an upright and fallen position.

My improvements have relation to that class of cuspadores of which the patent of Heath, dated October 10, 1871, No. 119,706, shows the princip1e -Viz., a loaded base to self right or counterbalance the vessel when upset; and my invention has for its object to improve the meclanical construction ot' these articles, so as to dispense with the double loaded botton heretofore generally used, and to better adapt them to be made of light material, such as spun metal or papier-mache.

My invention consists in making the throat, breast, base, and bottom of material such as suggested, of even, or about even, thickness throughout, such thickness being as slight as may be consistent witl strength, and in providing a eounterbalancing and strengthening ring or collar located at the illllCtiODOF joint of the breast and base, said ring or collar beig of such gravity as to cause the vessel to self-right when upset.

Referrin g to the accompanying drawing, A designates the flaring threat, B the breast, C the base, and E the bottom, of a euspadore of the usual form or shape. These parts are designed to be made ot' light material, such as spun netal or papier-mache, and to be of the sane or even thickness throughout, there bein g no double bottom, such as is generally employed for loading purposes.

1) represents a leavy ring or collar, nade preferably ot' cast-iron, and affixed to the cuspadore, either inside, as shown in Fig. 2, or

outside, as show in Fig. 1, below the breast and at or about the junction or joint of said breast with the base.

If spun metal be employed as the material for making the vessel, the edges of the breast and body will be turned over or lapped upon the ring or collar D; while it' papier-mache' or equivalent naterial be employed it will be formed or molded os'er or around said ring, either wholly or in part. Said ring, as already suggested, must be of such gravity as to cause the vessel to self-right after being upset. It also subserves the further valuable purpose of strengthening and staying the vessel on the line where it is usually touched by the foot in moving along the floor, and which also strikes the latter when the vessel upsets. It thus permits the vessel to be nade of very light material, and yet possess great strength and endurance.

As the bottom of these and kindred vessels is the part which usually wears out first, owing to the corrosion resulting from moisture, and as this vessel has a bottom of single thickness, it follows that a spun-metal euspadore constructed with the inprovement herein described can have a new bottom inserted, when required, by any common tin smith at sli ght expense, whereas when a double bottom for holding the loading, such as heretofore las been generally employed, becomes worn out it cannot be replaced except by an expert, and at considerable expense.

hat I claim as my invention is- A cuspadore havin g a flarin g tlroat, breast, base, and bottom ot' even thickness through out and a heavy ring or collar secured tlereto at the intersection or joint of said breast and base, serving to brace and strengthen the vessel at said joint, and to seli right it when upset, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 11th day ot' August, 1877.

SAML. J. VAN STAVOREN.
